Chris Riccomini commented on SAMZA-402:
---------------------------------------
Attaching a link to KAFKA-560. It's possible that we might be able to leverage
this feature to do atomic swaps with global state stores by having a data push
go to a new topic every time, and then updating the SamzaContainer to consume
from the new topic. This is a place holder so we don't lost the KAFKA ticket
that would allow the old topics to expire after some delay.
> Provide a "shared state" store among StreamTasks

> There has been a lot of discussion about shared state stores in SAMZA-353.
> Initially, it seemed as though we might implement them through SAMZA-353, but
> now it seems more preferable to implement them separately. As such, this
> ticket is to discuss global state/shared state (terms that are being used
> interchangeably) between StreamTasks.
